Abstract: A device for a head's up display comprises a picture generating unit; a projector optics; and a combiner. The combiner comprises a substrate made of optically transparent material and micro-optical structures arranged in a discrete array. The picture generating unit is arranged to deliver a beam of light, containing an image, to the projector optics. The projector optics and the combiner are arranged to form a virtual image of the image by reflecting a portion of the beam from the micro-optical structures. In the reflection, for at least a part of the beam reflected from the micro-optical structure, the resulting reflection deviates from the hypothetical reflection from the extrapolated substrate surface.

Abstract: A projection device is disclosed, wherein the projection device includes a lamp housing having a front portion and a back portion, wherein the lamp housing is configured to accommodate a lamp, a blower system configured to direct a flow of air across the front portion of the lamp housing, and a heat sink in thermal communication with the back portion of the lamp housing.

Abstract: Embodiments of methods and apparatus for cooling optics are disclosed.

Abstract: An apparatus (1) for recoating uncoated and spliced end portions of optical fibers (17) comprises two mold blocks (21a, 22b), each of which includes a groove (22a, 22b), the mold blocks being arrangable in a closed state, wherein the grooves cooperate to form a mold cavity for the fiber end portions, and in an open state, wherein the fiber end portions are insertable into the grooves. The apparatus further includes an injection system (5) for injecting a recoating material into the mold cavity, and a UV curing system (6) for irradiating the recoating material with UV light, thus curing the recoating material. At least one mold block is made of a plastic material comprising a fluoroplastic, e.g. PCTFE, the plastic material being at least partly transparent to UV light to enable the curing system to irradiate the UV curable recoating material with UV light through this mold block.
